Right. With the fallible allocator (which is what Sequence uses), the one-arg signature of AppendElement is protected. The two-arg signature that takes a const fallible_t& second arg and returns a boolean indicating whether the append succeeded.

Same thing: you have to use the fallible version and handle failure.

OwningNonNull can't be constructed from a pointer, because the assumption is that it should never store null and pointers can be null. It can be constructed from a reference, though.

So this should be: aResult.mNodes.AppendElement(*node); assuming node is not null, of course.

Which is what this helpful error message said, pretty explicitly. ;) -Boris _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
